Now this is an interesting approach, building further upon Uncontrolled Components: The React Hook Form (react-hook-form) library provides a new form validation mechanism which embraces uncontrolled form validation and support controlled components. The core idea is to register HTML input’s ref into the custom hook and therefore subscribe to its input value, validate and evaluate […]

Made with WebAssembly
After several Twitter threads on highlighting use cases, projects, and companies in production using WebAssembly, myself and a few other Wasm communitty members thought it’d be a great idea to have a dedicated place to find projects using WebAssembly, and highlight what WebAssembly can be used for! Some interesting stuff to find in there, like […]

Upgrade to PHP 7.4 with Homebrew on Mac
Brent has done a writeup on how to upgrade your Homebrew-installed PHP version to PHP 7.4. Since the php formula now contains that 7.4 version (instead of 7.3 before), all you need to do is make sure brew is up-to-date and then upgrade the php formula itself: # make sure brew is up-to-date brew update […]

Ire Aderinokun, author of the CanIUse Embed, has added an extra option where you can embed static images of features as mentioned on CanIUse.com.

24ways – the advent calendar for web geeks – is back! First post is “Making a Better Custom Select Element” in which Julie Grundy tries to create an accessible Custom Select Element: Sometimes, I can’t recommend the select input.

I like this nuanced post by David Barral in which he goes over all the options on how to configure a Confirm component: what exactly do you pass in as props. In this story we are going to see a simple technique that allows you to write friendly customizable components with simple APIs, just by […]
The Power of the JSON.stringify() replacer parameter
As previously detailed (2013 😱), you can use JSON.stringify()‘s second replacer parameter to pluck specific fields from it, by passing in an array: var person = {"name":"Jim Cowart","location":{"city":{"name":"Chattanooga","population":167674},"state":{"name":"Tennessee","abbreviation":"TN","population":6403000}},"company":"appendTo"}; JSON.stringify(person, ["name", "company"], 4); // ~> "{ // "name": "Jim Cowart", // "company": "appendTo" // }" As Pawel explains the parameter can also be a function, to […]
Manage React State with zustand
Small, fast and scaleable bearbones state-management solution. Has a comfy api based on hooks, that isn’t boilerplatey or opinionated, but still just enough to be explicit and flux-like. import create from 'zustand' const [useStore] = create(set => ({ count: 1, inc: () => set(state => ({ count: state.count + 1 })), dec: () => set(state […]
